T 0 all whom may concern Be it known that I, JULns EUGENE MALI- vnRr, a citizen oif the French Republic, of 9 and'll Rue du .Tlgraphe, Paris, France,

have. invented aIReheating Devicefor Soldering Irons, of which the following is a full, clear, and exact description. H

Thisjjnvention relates to a reheating device applicable to soldering-irons, soldering lanips-and various heating-and lighting apparatuses operating with gasoline and other volatile fuels t In these apparatuses, for instances, in solderingi1'ons is provided a device called gasifier where theiuel is vapori zedby rise of temperaturey'this rise of temperature is obtained by the transmission of heat coming from the device where the combustion takes place. the gasifier being suflioiently near the said device. t

!This system operates ingood conditions in most of the ordinary surrounding tei'mpera-v tures but in cold weather, the gasifier may not be brought to a temperature sufiiciently high for ensuringthe proper vaporization of the gasoline. l t

This invention relates to a movable. do vice, easy to put in position and remove, adapted to effect a reheatingof the gasifier when it is necessary. r Y Tl .'s 'd vice consists, substantially in a conduit which collects all or a part of the combustion products and brings them back into contact with the gasifierwhich is thus head capable of being set, so as to permit itsapplication in the case of the apparatuses where the soldering-iron itself is capable-of being set. g

The head is c rcular and'can rotate 111 a recess of corresponding ,shape, so that the chamber where the combustion of the gaseous products coming from the gasifier takes place issubstantially closed and that. the

combustion products are forced to enter the reheating conduit. I

In orderthat the inyent on maybe understood, its apphc'ationto a soldering-iron, is

illustrated in the accompanying drawing,

given by way of example only, in which:

Fig. 1 is an elevation of a soldering-iron provided with the new device.

Fig. 2 is a corresponding plan view.

Figs. 3 and 4 are two cross-sections re-;

. plan views of Fig. 6. I 1

Fig, 10 is a section online A.-A of Fig. 9. Figs. 11, and 13 illustrate separatelye. the head capable of being set, in elevation, side and plan views. I 7 willbe seen in the drawing, thesoldering-iron. to which the invention is appliechcomprise-s a handle a or reservoir, an element 7) constituting the ga-sifier and a burner 0. A removable armatured carries the soldering-iron proper e. 3 The reheting device is constituted, for instance, by a. piece of sh et iron 50 shaped to form apart f which fits on the rounded. cndof the armature (Z, aipart forming a conduit and a terminal, portion h, having two cheeks alaterally embracing the gasifier. When the temperatureis found to be suf ficiently' low for necessitating the putting in position of the reheating device, the securin bolt j is removed and the device is adapted on the .soldering-iron. care being.

taken to engage the cheeks i under the branches is of the armature of the soldering-iro-n, The bolt jfis replaced and the fixation is completed by' neansof a pin Z.

WVi-th this arrangement, the combustio products, instead ofbeingevacuated directly in the atmosphere, sent into. the conduit .9 and'pass around the gasifier b, as indi cated by the arrows, in order to finally issue in the atmosphere.

For regulating the intensity'ofthe reheat ing, thedevice is providedwith a regulating element permitting to direct a greater or less portion of thecombustion productson the gasifier. This element may consistior instance in shutter m. rotating fat 01/, on

openingunore or less-this shutter, a. portion of the combustion products can be directly evacuated in the atmosphere and thereheating can be controlled. I

Instead of a rotating shutter. a rotating ring covering theorifices, a sliding shutter or any other appropriate arrangement may be used. Y

In the arrangement illustrated in Figs. 6'

Figs. 1;]; to 13, also shown in section in Fig;

9 andwhich comprises two circular cheek s (Z connected on a portion or thelr periphery by a cylindrical wall (Z having a socket (Z adapted] to receive the solderingiron 6,

which is'secured by a screw 0 The reheating device carried by an armature constituted by two cheeksf per forated with holes so as to lighten them and facilitate their coolingJ These cheeks are terminated by branches in and are connected to each? other by a metallic strip 0, the ends 0 o 'of'which are rounded concentrically with the head capable of being set,-and having a round window p, Fig. 10, adapted to serve as a passage for the nose of the burner and a rectangular window 5 through which the combustion products are brought back into the reheating conduit 9. The latter is constituted by thin sheet iron plates forming a conduit of square cross-section occupying the spacebetween the two branches k. These sheet iron plates are terminated by checks 2' similar to those of the apparatus above mentioned. i

The adjusting hinged shutter 71%, rotating at n, is controlled by a hand knob m From Fig. 9 it will be easily understood that the soldering iron maybe given any desired inclination, it can be immobilized in any given position by tightening theinut s of a bolt 8 axially passing through the checks of the sheet iron plates capable of being set. 4 v

j The shutter m occupying the position 1, illustrated in full lines, the combustion products follow the direction indicated bv the arrows and thus come into contact with the.

. reheating, the shutter m is turned to a greater or less extent, and if it is desired to omit this action the shutter is brought to the position 2 indicated in dotted.lines;.the gases then issues in the atmosphere.

The arrangements above set forth are given by way ofexample only; the forms, dimensions, materials employed and all detail arrangements may vary according to circumstances without departing thereby 7 from the scope of the invention.

'Claimsz. V 1.,A reheating device for soldering. irons andvsimilar apparatus, comprising a'removable casing Which is placed over the. iron when the temperature is low, said casing including. a combustlon chamber at its forward end, and a conduit leading from the combus-.
